We are building a four story townhouse, narrow but tall. I would really like to be able to unlock the front door (and possibly have a doorbell that calls my phone and a camera/speaker to see and talk) without going down several sets of stairs to let someone in.
Lots of walk up apartment buildings have intercom systems to talk to and buzz in guests. I might have been looking in the wrong places, but I can't find any information about them, or less commercial and cheaper alternatives. Can anybody point me in the right direction? I could see putting in a wireless doorbell and wifi camera with speaker very cheaply, but then I can't figure out the lock. Something like doorbot and lockitron might help, but it looks unreliable, or at best untested. Any help would be appreciated.
